To all 1071 am it may concern:

Be it known that 1, ROBERT Z. FARMER, a citizen of the United States, residing at Bisbee, in the county of Cochise and State of 4'l of Fig. 3, with the rotor omitted; Fig. 5 is a fragmentary elevational view of the Serial No. 880,262.

stator as illustrated in Fig. 4; Fig. 6 is a fragmentary sectional view illustrating a second bucket wheel herein embodied; Fig. 7 is a fragmentary view, partly in section rectly with the track-way 4. I

In order that my invention may be the Mounted for reciprocating movement better understood, I will now proceed to dewithin the cylinder 6 intermediate the describe the same with reference to the aclivery ends of the ports 7 is the piston 9 companying drawings, whereinoperatively engaged in any desired manner Figure 1 is a side elevational view, with with the rod 10 projecting beyond the oppoa part in section, of a motor constructed in site extremities of the cylinder 6, the free accordance with an embodiment of my inextremities of said rod 10 being in contact vention; Fig. 2 is a horizontal sectional view with the continuous track-way 4, as is partaken substantially on the line 2-2 of Fig. ticularly illustrated in Fig. 2. In order to 1; Fig. 3 is a sectional view taken 'substanreduce to a minimum the possibility of any tially on the line 3-3 of Fig. 2, with the resultant friction, I find it of advantage to rotor in a differing position; Fig. 4: is a sechave operatively mounted in each extremity tional view taken substantally on the line of the rod 10 the roller 11 which contacts di- 11o embodiment of my invention, for the purpose of supply and exhaust and the projected extremity of each of the trunnions is inclosed within a boxing 12 mounted for axial rotation relative to the trunnion 5 independently of the rotary movement of the trunnion proper, and such boxing is provided with a supply port 1 1 and an exhaust port 15 preferably in substantially opposite relation and the flow through each of the ports 1t and 15 is under control of the valve 16 normally maintained in closed adjustment under the influence of the expansible member I? in a manner which believed to be self-evident.

As is believed to be clearly apparent to those skilled in the art to which my present invention appertains, it is necessary that the valves 1G be operated in unison but in reverse directions and as herein embodied the requisite adjustment of the valves is accomplished through the medium of the reversely disposed cams l8 enacting with the stems 19 of tl e valves and by which arrangement, it will be readily perceived, especially as is illustrated in Fig. 2, that the exhaust valve 16 will be closed when the delivery valve is open and vice versa. The cams 18 serve as a timed means for controlling the opening and closing of the respective valves 16, and it will be readily appreciated that by adjusting the time of operation of the cams 18, the dirction of travel of the rotor may be determined. As herein set forth, the independent axial movement of the boxing 12 permits of a ready reversal of the rotor, and in order that the necessary movement may be imparted to the boxing I have suitably secured thereto the lever 19 provided with a conventional spring latch 20 coacting with the rack 21, herein disclosed as operatively supported by the base or pedestal 2. In my present disclosure, two boxings 12 are employed and in order that the same may be axially rotated or rocked in unison, I find it of advantage to have the respective levers 19 suitably timed or connected, as indicated at 22 in Fig. 8. In view of this simultaneous operation of the respective levers 19, it will be appreciated that the latch 20 may be omitted in connection with the second of the levers.

In order to prevent displacement of the boxings 12 from the trunnions 5, I find it of advantage to employ in connection with each of the racks 21 a cross bar 28 overlying the forward face of the adjacent boxing 12 and provided with a suitable opening 2 1 through which the lug 25, produced at the axial center of'the forward face of the boxing, projects. This construction is believed to be fully illustrated in Figs. 1 and 2.

In communication with each of the supply ports 14: is a conduit 26 leading from a suitable source of supply and having interposed therein the controlling valves 27. As herein set forth, I have the supply conduits leading from a common main 28 in which is also interposed a controlling valve 29. It is also to be observed that the portions 30 of the supply conduits in direct connection pvith the induction or supply ports 14: are flexible in order to afford no hindrance to the axial adjustment of the boxings 12.

While in practice I have found that a motor constru ted in accordance with an embodiment of my invention, as hereinbefore set forth, substantially reduces to a minimum the possibility of a dead center, I find it of advantage to employ additional means to positively prevent such occurrence. As herein embodied, I suitably affix to each of the trunnions 5 a bucket wheel 31 disposed in reverse relation and delivering through the stator 1, as particularly illustrated at 82, at a predetermined point relative to each of the bucket wheels 31 is a conduit 33 leading from the exhaust conduit 3% common to both of the exhaust ports 15, and said conduit 33 has interposed therein the controlling valve 35 whereby the discharge may be readily regulated in order to coact with the requisite bucket wheel 31, as dependin upon the direction of rotation of the rotor. It is also to be observed that the end portions 36 of the conduit 34- directly in connection with the ports 15 are also flexible in order to afford no obstruction to the axial adjustment of the boxings 12.

In order that the exhaust delivered upon the respective wheels 31 may be readily dclivered to the atmosphere, I provide at a proper point relative to each delivery point 32 a port 37 as is particularly illustrated in Fig. 1, and I also find it of advantage to have each of the wheels 31 in close proximity to a head or side plate 3 so that a single segmental flange 38 may be employed for bridging the space between each. of the points 32 and port 37 in order to properly confine the exhaust.

While my motor, as herein embodied, is primarily intended to be operated by compressed air, I do not wish to be understood as limiting myself in this particular, as steam or any other expansive force may be employed with equal facility, and if under requisite tension 1 have also found that water may be employed.

From the foregoing description, it is thought to be obvious that a motor constructed in accordance with my invention is of an extremely simple and comparatively inexpensive nature and is particularly well adapted for use by reason of the convenience and facility with which it may be assembled, and it will also be obvious that my invention is susceptible of some change and modification without material departure from the principles and spirit thereof and for this reason I do not wish to be understood as limiting myself to the precise arrangement and formation of the several parts herein shown in carrying out my invention in practice.

I claim:
